Internet-based EDI is emerging as a prominent substitute technology for traditional VAN-based EDI technology. The strength of this new technology is based on the explosive growth of Internet community, low "fixed-rate" Internet expense and "globally" open base of its participants. These strengths of Internet-baed EDI bring vast new opportunities for enterprises and thus. have as much implications for IT managers. However, Internet-based EDI technology has, at least by now, several drawbacks too. Most of these drawbacks also comes from the fact that it has its structural base on the Internet. Managers should carefully consider these drawbacks and hidden costs before adopting or switching to this attractive new technology. This presentation attempts to address major trends of Internet-based EDI and its implementation, opportunities and threats of the changes in technology, factors to consider in adopting this technology, and several managerial and strategic tradeoffs and implications of Internet-based EDI for IT managers.

This study was carried out to evaluate the effects on elementary school children of Internet-based nutrition education programs. The subjects consisted of 80 boys and girls (book-loaming group : 42, Internet-based teaming group : 38) in the 5th grade of elementary school. The results were as follows : The evaluation of Internet-based education programs by Internet-teaming group showed above average in all domains. As the favorite and wholesome menu chose‘nutrition kingdom’(52.6%) made of animation. The educational effect of this program was evaluated by comparing the methods of the Internet-learning group with those of the book-learning group. For effect-evaluation were measured the degree of nutrition knowledge and diversity score of dietary intake from before and after education. Before undertaking the program, there was no significant difference between the two groups in terms of their nutrition knowledge. However, the nutrition knowledge of the Internet-based teaming group after the program had increased significantly (p < 0.01) compared to the book-learning group. There was no significant difference between the two groups in terms of the diversity of dietary intake before the start of the program, but upon its completion, the Internet-based learning group showed a significant increase compared to the book-loaming group (p < 0.05). This suggests that Internet-based educational programs could be effective in drawing the interest and boosting the concentration levels of schoolchildren. In conclusion, Internet-based nutrition education shows the potential to be an effective alternative education method. (Korean J Nutrition 36(5): 500∼507, 2003)

The purpose of this study is to find out the effects of internet resource-based problem-based learning on the academic achievement in science and the attitude toward science of elementary school students. One experiment class and one control class of grade 6 students were selected to perform a prior investigation on the academic achievement in science and the attitude toward science, then the experiment class attended 4 weeks of lessons that was applied the internet resource-based problem-based learning, and the control class attended the traditional lessons based on the guidelines of teachers. After conducting lessons, a post investigation was performed for each class and the results were analyzed to produce the following conclusions. First, the internet resource-based problem-based learning could be seen to be effective in improving the students' academic achievements in science. The internet resource-based problem-based learning seemed to make students recognize the lesson details better and grasp well the questions given during lessons from the process of finding solutions among many informations and data on the internet. Second, the internet resource-based problem-based learning had a positive effect on all attitudes' areas toward science of students. It looked like that the internet resource-based problem-based learning taught the students to use the internet resources and gave them a friendly feeling, so the children could actively participate in class and had positive recognition on science. Third, from teacher observation and the result of the student recognition investigation, we could know that the students showed lots of interests in the internet resource-based problem-based learning, and they were able to understand the scientific theories in the process of solving problems that were relevant to real life, and thought science in a positive way.

인터넷을 기반으로 한 커뮤니케이션은 폭발적으로 증가해 왔고, 현재는 우리 일상에 자리 잡고 있다. 인터넷 커뮤니케이션은 이전의 커뮤니케이션 방법과는 다른 방식의 소통 방식으로 인식되고 있으며, 이에 대한 많은 연구들이 진행되어 왔다. 인터넷 관련 연구의 가장 중요한 주제 중 하나는 인터넷 기반 커뮤니케이션이 인간관계에 미치는 영향이었다. 인터넷은 경제적, 정치적 이익이 있는 반면, 인간관계, 인간의 삶에는 다소 부정적인 영향이 있을 것이라고 주장되었다. 인터넷의 부정성은 기본적으로 인터넷의 익명성에 기초한다. 인터넷의 익명성으로 인한 인터넷 포르노그라피에 대한 무분별한 노출, 악성댓글, 인터넷 게임중독, 개인정보 유출과 같은 인터넷의 부작용들이 보고되었고, 이러한 현실적 문제들은 인터넷의 부정적인 영향을 주장하는 쪽에 힘을 실어주었다. 하지만 최근에 진행되고 있는 인터넷 관련 연구들은 인터넷의 부정적인 측면 뿐 아니라 인터넷의 긍정적 영향에도 관심을 갖기 시작했다. 인터넷이 사람들의 삶과 인간관계에 부정적인 영향을 준다는 입장에 선 학자들은 인터넷이 현실을 대체한다는 관점에서 인터넷의 부정성을 지적하고 있다. 인터넷이 면대면 대화를 줄이고, 현실을 일정부분 대체하게 하면서 여러 가지 부작용이 나타나고 있다고 주장하고 있다. 그러나 인터넷이 삶에 긍정적인 영향이 있다는 관점에서는 개인의 인터넷 사용동기, 목적을 강조하면서 인터넷 보다는 사용자에 초점을 맞추고 있다. 이 패러다임에 따른 연구들은 인터넷이 인간관계의 물리적 제약들을 해결해줌으로써 인간의 삶, 인간관계 등을 확장해준다고 주장한다. 또한 인터넷의 부정적 특징으로 여겨지는 익명성도 도리어 새로운 만남을 보탬이 될 수도 있다고 주장되고 있다. 인터넷에 대한 두 가지 입장은 각각 자신들의 입장을 지지하는 결과를 도출해 내고 있지만 두 입장의 간격을 쉽사리 줄여지지 않고 있다. 본고는 인터넷에 대한 두 가지 입장을 정리하고, 향후 인터넷이 우리 삶에 미칠 수 있는 영향에 대해 통합적으로 검토하고자 하였다.

Recently, new network systems have begun to emerge (for instance, 5G, IoT, and ICN) that require capabilities beyond that provided by existing IP networking. To fulfill the requirements, some new networking technologies are being proposed. The promising approach of the new networking technology is to try to overcome the architectural limitations of IP networking by adopting an identifier (ID)-based networking concept in which communication objects are identified independently from a specific location and mechanism. However, we note that existing ID-based networking proposals only partially meet the requirements of emerging and future networks. This paper proposes a new ID-based networking architecture and mechanisms, named IDNet, to meet all of the requirements of emerging and future networks. IDNet is designed with four major functional blocks-routing, forwarding, mapping system, and application interface. For the proof of concept, we develop numeric models for IDNet and implement a prototype of IDNet.

The exponential growth of the Internet has been the advent of buying and selling products and services over the Internet. In Korea, electronic commerce including Internet commerce reached a ￦6,534 billion industry in the year 2002. This paper presents the importance of understanding and managing consumer trust to sellers succeed in Internet commerce. We tested a trust model that includes seller's trustworthiness-based factors and consumer's personality-based factors. We found that seller's trustworthiness-based factors lead to greater consumer trust in Internet shopping through the consumer's perceptions about integrity, benevolence, reputation, and size, but consumer's personality-based factors containing five traits, extraversion, agreeableness, conscientiousness, openness, and trust propensity, have not a significant effect on consumer trust. We also confirmed a positive relationship between consumer trust in Internet shopping and consumer intention to buy.

Purpose: This study aimed to investigate the maternal health effects of internet-based education interventions on parturients during the postpartum period through a systematic review of randomized controlled trials. Methods: An electronic literature search of the Cochrane Library, CINAHL, EMBASE, Eric, PsycINFO, PubMed, RISS, and KISS databases was performed, using the combination of keywords such as 'parenthood education', '*natal education', '*birth intervention', 'internet-based intervention', 'randomized controlled trial'. The inclusion criteria were peer-reviewed papers in English regarding randomized controlled trials of internet-based postnatal education interventions. Educational interventions were delivered through any web, mobile, eHealth, mHealth, virtual reality, short message service, or social networking service platform. Quality appraisal was performed using the Risk of Bias 2 (RoB 2) for randomized controlled trials. Nine articles were yielded, and the intervention effects were analyzed. Results: Internet-based education interventions during the postpartum period affect maternal self-efficacy, postpartum depression, and successive breastfeeding; however, they do not affect maternal satisfaction and parenting confidence. Conclusion: This study demonstrated that internet-based education interventions affect maternal health status in terms of psychological, emotional, and physical wellness. Therefore, maternal health care professionals can utilize remote education using the internet or mobile-based interventions during the postpartum period.

With the rapid growth of the Internet, the Internet-based robot has been realized by connecting off-line robot to the Internet. However, because the Internet is often irregular and unreliable, the varying time delay in data transmission is a significant problem for the construction of the Internet-based robot system. Thus, this paper is concerned with the development of an Internet-based robot system, which is insensitive to the Internet time delay. For this purpose, the PPS (Position Prediction Simulator) is suggested and implemented on the system. The PPS consists of two parts : the robot position prediction part and the projective virtual scene part. In the robot position prediction part, the robot position is predicted for more accurate operation of the mobile robot, based on the time at which the user's command reaches the robot system. The projective virtual scene part shows the 3D visual information of a remote site, which is obtained through image processing and position prediction. For the verification of this proposed PPS, the robot was moved to follow the planned path under the various network traffic conditions. The simulation and experimental results showed that the path error of the robot motion could be reduced using the developed PPS.

Most banks in Korea have provided Internet banking services based on PKI(Public Key Infrastructure) certificates since the early 2000s when Internet banking began in Korea. To support PKI Internet banking, the Korean government backed the electronic signature law and supported the rapid spread of PKI-based Internet banking by regulating the application of PKI certificates to be compulsory in Internet banking until 2015. PKI Internet Banking in Korea has been developed as a pioneer in this field through many challenges and responses until its present success. Korea's PKI banking, which started with soft-token-based closed banking, has responded to various types of cyber attack attempts and promoted the transition to open banking by accepting various criticisms due to lack of compatibility with international standards. In order to improve the convenience and security of PKI Internet banking, various attempts have been made, such as biometric-integrated smartphone-based PKI authentication. In this paper, we primarily aim to share the experience and lessons of PKI banking by analyzing the evolution process of PKI Internet banking in Korea. It also has the purpose of presenting the challenges of Korea's PKI Internet banking and sharing its development vision.
